Please use Law of Cosine to answer!

Step-by-step explanation:

13.) option d. side side angel ( as it has 2 sides and 1 angle )

14. ) cosine

16 ) formula of law of cosine

c = √a² + b² - 2ab • cos c

c = √31² + 35² - 2 • 31 • 35 • cos (48°)

c = 27.09

hope this answer helps you dear

c

step-by-step explanation:

at least i think its

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
